Phenolic hydroxyl groups, carboxyl groups, alcohol hydroxyl groups react with sodium salts

1) C6H5-OH+Na2CO3 C6H5-ONA+NaHCO32C6H5-OH+2Na 2C6H5-ON+H2 reacted rapidly.

Because H2CO3 is more acidic than phenol, NaHCO3 does not react with phenolic hydroxyl groups.

2) 2R-CoOH + Na2CO3 2Rcoona + CO2 + H2O (R denotes hydrocarbon group or hydrogen atom).

RcoOH+NaHCO3 RCOONA+CO2 +H2O2RCOOH+2NA2RCOONA+H2 reacts violently.

3) 2RoH+2Na 2Rona+H2 (R denotes hydrocarbon group) reaction is slower.

Alcohol is a neutral substance and does not react with Na2CO3 and NaHCO3.

1. It can react with sodium: alcohol hydroxyl group (-OH), phenolic hydroxyl group (-OH), carboxyl group (-COOH).

2. It can react with sodium hydroxide: phenolic hydroxyl group (-OH), carboxyl group (-COOH), ester group (R-COO-R).

3. It can react with sodium carbonate: phenolic hydroxyl group (-OH), carboxyl group (-COOH).

4. Can react with sodium bicarbonate: carboxyl group (-COOH).

Sodium hydroxide is strongly alkaline and has strong hygroscopicity. Soluble in water, exothermic when dissolved, the aqueous solution is alkaline and has a greasy feeling; It is extremely corrosive and has a corrosive effect on fibers, glass, ceramics, etc. Hydrogen is released by reacting with metal aluminum and zinc, non-metal boron and silicon; disproportionation reaction with halogens such as chlorine, bromine, iodine; It neutralizes with acids and produces salt, Zen, percolation and water.

Carboxyl and sodium do not react, carboxyl is the basic chemical group in organic chemistry, all organic acids containing carboxyl groups can be called carboxylic acids, composed of one carbon atom, two oxygen atoms and one hydrogen atom, the chemical formula -COOH. For example, acetic acid (CH3-COOH) and amino acids contain carboxyl groups, and these carboxyl groups are directly linked to the hydrocarbon groups, which are called carboxylic acids.

Sodium is a metal element, located in the 3rd period, group a in the periodic table, is a representative of alkali metal elements, soft texture, can react with water to form sodium hydroxide, release hydrogen, chemical properties are more active. Sodium is widely distributed in the form of salt on land and in the sea, and sodium is also one of the important components in human muscle tissue and nerve tissue.

Reaction, -OH in the carboxyl group is combined with Na to form hydrogen.

Phenol, spindle.

Can react with sodium: alcohol hydroxyl group (-OH), phenolic hydroxyl group (-OH), carboxyl group (-COOH), carboxyl group (-COOH), ester group (R-COO-R) can react with sodium hydroxide, and phenolic hydroxyl group (-OH), carboxyl group (-COOH) can react with sodium carbonate.

The reaction with NaHCO3 requires hydrogen from acids that are more acidic than carbonic acid, while phenolic hydroxyl groups are weaker acidic than carbonic acid, so in the organic chemistry part, only hydrogen on the carboxyl group has this reactivity.

<> generally not. The acidity of the alcohol hydroxypxine group is not strong enough. The reverse reaction of this reaction can be carried out: sodium alk + water = alcohol + Naoh.

The hydroxyl group has the chemical formula -OH and is a common polar group. Hydroxyl groups are mainly divided into alcohol hydroxyl groups, phenolic hydroxyl groups, etc.

The hydroxyl group has some similar properties to water, the hydroxyl group is a typical polar group, and can form hydrogen bonds with water, and exists in the form of negatively charged ions (-OH) in the inorganic compound sailor dissolved finger fluid, called hydroxide.

The carboxyl group reacts with all the latter to form sodium salt and water with sodium hydroxide, and sodium salt carbon dioxide and water with the latter two. Hydrogen gas is released by reacting with sodium.

The alcohol hydroxyl group only reacts with sodium to release hydrogen. The rest do not respond.

Phenolic hydroxyl group and sodium release hydrogen gas to form sodium phenol, sodium phenol and water with sodium hydroxide, and sodium carbonate to form carbon or sodium ularate and sodium phenol, which do not react with bicarbonate.

The lipid group is hydrolyzed with sodium carbonate and sodium hydroxide to produce sodium salt and alcohol, and the former also releases carbon dioxide and trapped ears. Reacting with sodium, sodium first reacts with water to form sodium hydroxide, which reacts with it.

The aldehyde group is complex, and there will be a reduction reaction with sodium, which is partially reduced to alcohol, and sodium hydroxide will form alcohol and sodium carboxylate.
